Claims, (C1. zii- 34) This invention comprehends means to combine the function of annealing, shaping and cutting into a device for making orthopedic casts and supports from sheets of annealable material. The

5 advantage of use is simplicity of handling, ac-

curacy of ttinga piece to a model, and low operating costs. Present methods used in orthopedic work include plaster paris systems which are messy to apply and often become too tight and endanger the patient to. cuts when they are taken off. Other methods involve the use of heavy metal ill-fitting ready made supports which are expensive and are difficult to hold in place.

It has been found that certain materials are adaptable to the formation of casts or other orthopedic supports after being annealed. As cutting and shaping is only possible when the materials are heated to a certain temperature, it has formerly been impossible to shape such material to a living body for the purpose desired due to danger of blistering.

This device makes it possible to form casts and supports to the proper shapes with reference to the model so that only the top need be annealed after the cast is in place for complete closure if this last should be necessary.

The construction of the device embodied by the invention and the method of using same will be understood from the following detailed description and accompanying drawing in which:-

Figure 1 is a side elevation parts being shown in section.

Fig-ure 2 is a top plan view.

Figure 3 is a fragmentary view showing the method of forming a cast or similar orthopedic support.

Figure 4 is a view similar to Figure 3 with the shaping tool removed and a cutting tool in place.

Figure 5 is a perspective view of the shaping tool.

Referring to the drawing in detail the invention consists of a base or platform 1, having secured near one corner thereon an upright 2 bent at right angles at some distance above the base as at 8 and terminating in a depending sleeve or bearing 4. Slidably mounted upon this upright and provided with a set screw fo-r holding at any desired position is collar 5 carrying a supporting arm 6 to which is secured a Working table 7. This table is formed in two parts, each part being provided at one end with a slot 8. Having the table secured only at one end leaves the opening between the two parts entirely clear for the purpose which will be clearly obviousas the description proceeds. Passing thru slots 8 and through openings in the base 6 are clamping bolts 9. This allows the opening between the parts of the table to be fixed at any size that may be desired. Mounted for reciprocating motion in the sleeve 4, is a shaft 10, provided with a slot 11, in its midsection thru which passes an operating lever 12 pivoted at its inner end to the ears 13, formed upon the upright 2, and having a handle at its outer end. The sleeve 4 is slotted throughout the greater part of its length to provide free motion for the operating lever 12. Secured by bolts in a kerf in the lower end of the shaft 10, is a shaping tool 14. This tool has a series of openings to allow for different angular adjustments which may be deemed desirable or necessary in the formation of certain casts. Below the collar 5 and upon the upright 2 is placed another vertically adjustable collar 15. Mounted in a swivel 16 upon the collar 15 and adjustable longitudinally within the swivel is a rod carrying an electrical heating unit 17 for the purpose of bringing the material to be formed to the proper temperature for molding and cutting. This heating element may be swung completely out of the Way if at any time it is necessary to form a very deep depression in material being worked or it can be detached for use in completion of a cast to further anneal and shape material used.

The shaping tool 14 is detachable and when it is desired to cut the material being worked upon, the cutting tool 18 may be inserted into the machine.

The material to be shaped and formed is placed upon the table 7 and after heating same using heating unit 17 and then operating lever 12, the cutting tool 18 cuts the material to proper outline andthe forming tool 14 depresses the material into the opening between the parts of the table 7 to the proper shape. This latter operation is further aided by turning or rotating the material into the opening between the parts of table 17 according to the shape desired. After the proper form is obtained water may be v poured over the material to make it set quicklyrfor which proper pan indicated by dotted lines in Figure l may be used.

It is understood that this description does not limit the device to any particular shape or form, but includes al1 changes in detail which fall within the scope of the claims:

1. In a device of the class described, a platform and upright upon the platform, a slotted sleeve or bearing depending therefrom, a shaft mounted for recprocation within the sleeve, a

lever pivoted at one end to the upright and passing thru a slot in the shaft to actuate the same, an interchangeable shaping tool detachably secured to lower end of shaft, a table consisting of two or more sections slidably arranged to vary the opening between the sections adjustably mounted upon the upright and a heating means adjustably and detachably mounted on the upright on the opposite side of the table from the interchangeable shaping tools.

2. In the annealing, forming and cutting device, a support, an adjustable table mounted on the support comprising relative movable blocks the separation of which alone admits direct radiant heat to any desired portion or surface of material to be shaped, a radiant heating means mounted on the support beneath said blocks, said blocks supporting the work for operation thereon of suitable shaping tool.

3. In annealing, forming and cutting device for use in making simple structures such as ortho pedic casts from annealable material, comprising a suppport, with an adjustable table mounted thereon consisting of two or more sections slidably arranged to vary the opening between the sections, which arrangement permits direct radiant heat to strike only a desired regulatable portion of material to be formed, a radiant heating means mounted on the support below said table, said table to support material to be worked by suitable interchangeable shaping tool.

4. In a device of the class described a support, an adjustable table mounted thereon consisting of two or more sections slidably arranged to vary the opening between the sections for admitting radiant heat to any desired portion of material placed thereon, a radiant heating `element mounted below said table and means for detachably mounting a suitable shaping tool to top of said support for action on annealed portion of material.

5. In a device of the class described, a support, an adjustable table mounted thereon for placing hard rubber, Celluloid, certain alloy metal sheets, or other annealable material, said table comprising two or more sections slidab'ly arranged to Vary the opening between sections to control the source of radiant heat, a radiant heating element mounted on said support to radiate heat thru said adjustable opening to anneal portion of material placed thereover, and means for extension from support above said table for detachably connecting suitable shaping tools to act on annealed portions of material to be worked.
